- UTT HiPER 810G
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, network infiltration, and persistent backdoor installation.
Likely Case
Device crash causing service disruption, denial of service, or limited code execution for privilege escalation.
If Mitigated
Service disruption only if exploit attempts are blocked by network controls, with no persistent compromise.
🎯 Exploit Status
Proof of concept code is publicly available in GitHub repositories, making exploitation straightforward for attackers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: Yes
Instructions:
1. Check vendor website for firmware updates. 2. Download latest firmware version. 3. Backup current configuration. 4. Upload and install new firmware via web interface. 5. Restart device. 6. Restore configuration if needed.
🔧 Temporary Workarounds
Disable remote management
allPrevent external access to the vulnerable web interface
Access router web interface → System Settings → Remote Management → Disable
Network segmentation
allIsolate affected routers from untrusted networks
Configure firewall rules to restrict access to router management interface
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach the router management interface
- Monitor for exploit attempts using IDS/IPS signatures and block malicious traffic
🔍 How to Verify
Check if Vulnerable:
Check firmware version in router web interface: Login → System Status → Firmware VersionCheck Version:
Not applicable - check via web interface or SSH if enabledVerify Fix Applied:
Verify firmware version is newer than 1.7.7-171114 and test formPolicyRouteConf functionality📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /goform/formPolicyRouteConf
- Device crash/reboot logs
- Large GroupName parameter values
Network Indicators:
- HTTP requests with oversized GroupName parameters
- Traffic patterns suggesting buffer overflow attempts
